An agricultural product processing (roasting) system that uses solar power as the primary heat source. An embodiment includes two rotating hollow chambers for containing agricultural products, such as beans or nuts, during a roasting session. An array of heliostats concentrates reflected solar radiation onto the surface of each hollow chamber, typically one chamber at a time, while the other chamber is cooling or being serviced. The rotational velocity is controlled to ensure even heating from the solar heliostat array, and temperature and humidity sensors may be used to monitor and control the system. Various actuators control the rotational velocity, the opening or closing of vents or perhaps louvers, the directional pointing of the heliostat array, and the opening of a door to empty the hollow chamber after processing.

A bean roasting apparatus with a stirring barrel body, a receiving structure and an image capturing assembly is provided. The stirring barrel body has an opening. The receiving structure has a bean-through opening and an observation opening. The image capturing assembly has at least one image capturing device and a reflective surface which is disposed in the capturing scope of the at least one image capturing device and is tilted facing the at least one image capturing device and the observation opening. Therefore, the at least one image capturing device can capture an image inside the receiving structure through the reflective surface and the observation opening. Another bean roasting apparatus with an image capturing assembly is provided, wherein at least one image capturing device of the image capturing assembly can capture an image inside the receiving structure through the observation opening directly.
